Search and rescue efforts as well as damage assessment were under way in areas worst hit by floods with the help of six helicopters and 35 boats, it said.

On Tuesday, the Anatolia news agency quoted Tekirdag Governor Zubeyir Kemelek as saying six bodies were found in the Saray town of his province.

A total of 1,600 homes and business places had been devastated by floods in the towns of Silivri and Selimpasa in Istanbul province, Turkish Minister of Environment and Forestry Veysel Eroglu told reporters earlier on Wednesday.
